The TelessaúdeRS / UFRGS becomes freely available RegulaSUS the application, new support tool for doctors of Primary Health Care (PHC). The RegulaSUS application was created to facilitate access to routing protocols developed by TelessaúdeRS / UFRGS in partnership with the Secretary of State of Rio Grande do Sul Health.From quick and easy access, on your smartphone screen, PHC doctors may consult if patients show clinical criteria suggest referral to the specialist. The grounds set out in the protocols available in the application, are the most prevalent in referrals to specialized services. We point out that other medical conditions, or found in the history and physical examination of patients may justify the need for evaluation to the expert, even if not included in these protocols. So it is important to describe all the relevant information at the time of referral.We hope that the routing protocols offered by TelessaúdeRS / UFRGS, and made available on RegulaSUS application, allow better access to specialized services, by defining clinical criteria suggest referral to other levels of care, thus increasing the resolution and the coordinating role of the APS .
